wrangler Advance Adapters Gearing - driveshaft - Photo 18337567

Here's the setup before, with the NP231 sporting its slip yoke eliminator and 1310-CV driveshaft. The rear shaft measured 17 1/4 inches from the center of the rear driveshaft U-joint to the center of the U-joint at the CV. For the curious, Miller was able to retain his front driveshaft, as the before-and-after swap measurements remained the same at 42 inches between U-joint centers.
